Checkbox toggle square getting lost-CodePudding

I have been working on a custom-styled checkbox, but for some reason, the square when the toggle is checked is getting lost.

Anyone could please point out what I did wrong with this checkbox?

          <input type="checkbox"  id="default">
          <label for="default" data-checked="Checked" data-unchecked="Unchecked"></label>      
        </div>
        
     </div>
   </body>

I believe is something to do with the before and after where I'm forgetting to set some value.

CSS

  padding-top: 30px;
  color: white; 
}

input[type=checkbox].toggle{
  display: none;

  display: inline-block;

  transform: translateY(-50%);
  text-overflow: ellipsis;

 }

input[type=checkbox].toggle:not(:checked)   label{
 background-color: transparent;
 text-align: right;
}

input[type=checkbox].toggle:not(:checked)   label:after{
  content: attr(data-unchecked);
  right: 0;
  left: auto;
  opacity: 1;
  color: white;
}

input[type=checkbox].toggle:not(:checked)   label:before{
   left: 4px;
   background-color: white;
}

input[type=checkbox].toggle:checked   label{
   text-align: left;
   border-color: yellow;

input[type=checkbox].toggle:checked   label:after{
   content: attr(data-checked);
   left: 4px;
   right: auto;

CodePudding user response：

When the input is unchecked then the before pseudo element is given a background color of white.

When it is checked then it is given a color to the border, but the border has not been given any width.

Assuming you want a yellow bordered square the this snippet not only sets the border color but also solid and 1px width.
